Your name or email address: There are millions of these vintage chips out there in old 70’s electronics junk. The Satasheet drives things harder and it is tighter and crisper. I’m just curious, because most pedal experts seem to concur that both old and current production chips from different parts of Asia all tend to sound consistently the same.

In addition, the JRCD was used in tons of Japanese audio equipment at about the same time, so a fatasheet cheap Japanese stereo or clock radio could have several hidden inside it. When you order these, you get parts that are labeled “JRC”.

May 23, 1. Even the slew rates, which some believe gives a hint to what makes the ‘ good, were all different. I’m just wondering where things currently stand.

If you want “vintage Tube Screamer” then this is the best choice probably. I started researching TS’s quite a long time ago. Saying that the ‘ is the best dual opamp for a TS type pedal is like winning the lottery the very first time you play. What have y’all overheard at the musician’s watercooler discussions? May 24, 5. I replaced the two output resistors with carbon film resistors I had laying around, and I just order a couple of new RCP’s for 25 cents a piece.


I have another clone of the same circuit that I paid datasjeet less for and it shows.

It’s a demonstrable fact that the tone quality of op amps varies significantly. Catasheet don’t dqtasheet I went overboard with the cost on this one.

Robbie WMay 24, One of the 9’s was beefed up with better i. There are probably 3 that most guitarists would agree sound ‘bad. If you’re doing this to a TS 10, short out the 1K resistor leading to pin 3 of the dual opamp as well.

Put a TL in there and be prepared for an overly bright dataaheet brittle sound. Some circuits sound better with inferior spec’ed chips. I attribute the superior tone to the builder of the box.

And is anyone aware that the TS7 has the “correct” chip and output resistor values? Sorry to kick over any sacred cows but this is just my opinion based on my experience.

May 24, 6. I wish I dztasheet say that it sounded noticably better but the TL that I put in the amp did! I yanked it out and put it in my TS5. May 23, 4. Are the misinformed still spending 30 bucks or more for a “NOS” chip, and 2 “brown sound” resistors?

I will go as far to say ALL ‘s sound so similar I doubt anyone could hear a difference in a blindfold test.

May 24, 8. However, the odds that they’ll hear a difference are very good, and if there’s an audible difference, multiple listeners will have consistent preferences.

I sent Analogman my TS-9 several years ago and had him replace the chip and beef up some weak spots with no other jrrc4558 and it came back as he described: Jrd4558 TS’s have the Ibanez R “trademark” logo which datasheer people seek. As far as ‘s in general I will say this. My unscientific conclusion was that the best chip probably has yet to be found.


I then went on to check the specs of each ‘good’ chip. On the other hand, I also think we all at least I have personally tried some of the products on the idea of “if I can afford it, what can it hurt?

This is where the rec. Clever marketing can take advantage of this to sell a ten cent amp for ten bucks. Several electronics suppliers list the JRC We have not lost technology over the years, like we have with tubes, we have taken the same technology and made it cleaner in the case of silicon. And I started probing really deep around the time that Analogman started offering their wares, oddly enough. The in a Tube Screamer does have a sound that is good and is what a lot of people find to their liking.

Back to theI think that people are just applying NOS ideas to the chips like they do tubes. Both have jrf4558 JRC There is nothing magical about the “new old stock” Jrv4558 that constitutes spending too much money for a “vintage chip”.

May 24, It’s eatasheet how some of these falsehoods prevail. On the other hand, “better” and “vintage” aren’t necessarily the same thing, even though they get jumbled together in our sorry little heads.

Yes, my password is: I put this in the same piles as some of the capacitor, resistor and conductor stuff floating around. They had nothing in common.
